PROGRAMMING 18. SPECIFYING THE LASER FUNCTION
At the transition from block A to block B, machining is performed as
Block A Te Lr
Fa : Feedrate of block A
Sa : Output peak value of block A
Pa : Pulse frequency of block A
Qa : Pulse duty cycle of block A
Se : Piercing output peak value
Pe : Piercing pulse frequency
Qe : Piercing pulse duty cycle
Te : Piercing time
Lr : Return distance
Fr : Return feedrate
Pr : Return frequency
Qr : Return duty cycle
Fb : Feedrate of block B
Sb : Output peak value of block B
Pb : Pulse frequency of block B
Qb : Pulse duty cycle of block B
Data of block A
Edge machining data
Data of block B
(1)A gradual stop occurs at the end point of block A.
(2)The output is held until a gradual stop occurs.
(3)Piercing is performed at the top of the corner.
(4)Upon the completion of piercing, a block B movement starts.
(5)Before switching to the machining condition of block B, the feedrate
is changed to the return feedrate until the amount of travel equals the
return distance. Then, the output peak value, return frequency, and
return duty cycle for block B cutting are set for startup.
(6)When the return distance is moved, machining is continued by
switching to the machining condition of block B.
1 As the return distance, a value exceeding the length for one
block cannot be specified.
2 Return peak value Sb’ can be set in parameter No. 15059.
It is set when as output peak value Sb’ over distance Lr, a
value different from peak value Sb for block B is to be set.
When this value is set to 0, machining is performed on the
assumption that Sb’ equals Sb.
